I am playing on the NA servers for PC.
I am attempting to do the quest "Through the Shroud". The quest asks me to use the gray jar near the npc. The tooltip telling me to press E to use the gray jar pops up, I press E and nothing happens. I press it again and it says "Item not ready yet". Since pressing E doesn't work I went into my inventory, right clicked the quest item and selected "Use". That also did not work.
I have tried disabling all of my mods. I tried abandoning the quest and logging off for an hour.
I know the quest works for other people because I have seen many people come in, drink they potion, and turn into a skeleton.
I am not sure what to do at this point. It's a bit frustrating since I have been saving up for the Autumn's Gate house since homestead came out and now I can't do the quest line to get the achievement needed.
